Abstract
The invention discloses a novel circular lubricating cold drawing inner die and relates to the technical field of non-ferrous metal machining. The novel circular lubricating cold drawing inner die comprises an inner die body (1), circular flow channels (2), small holes (3) and oil outlets (4). The multiple circular flow channels (2) are formed in the inner die body (1) in a staggered mode. The multiple small holes (3) are formed in the tail portion of the inner die body (1). The multiple oil outlets (4) are formed in the middle portion of the inner die body (1). The small holes (3) and the oil outlets (4) are all communicated with the circular flow channels (2). According to the novel circular lubricating cold drawing inner die, the heat of a working tape and a deformation zone of the cold drawing inner die is reduced, and the probability of size contraction of the inner die due to polishing is decreased, so that the stability of the size precision of products is improved and the cost for purchasing the die is reduced.
Description
Technical field:
The present invention relates to technical field of nonferrous metal processing, be specifically related to a kind of novel lubrication cold drawing inner membrance capable of circulation.
Background technology:
Internal mold is a requisite mould in cold drawing process.
The drawing internal mold that market uses at present be can not circulating lubricating cold drawing core print, and after the aluminum pipe of the certain tonnage of every drawing, core print easily glues aluminium, and employee needs regular polishing internal mold, has had a strong impact on the production efficiency of product and the endoporus quality of product; Frequent due to polishing number of times, can cause the size of internal mold to reduce because of polishing, thus can reduce the dimensional accuracy of product and improve the cost of buying mould.
Summary of the invention:
The object of this invention is to provide a kind of novel lubrication cold drawing inner membrance capable of circulation, that reduce the heat of cold drawing internal mold work strip and deformed area, decrease the probability that the internal mold size that causes because of polishing reduces, thus improve the dimensional accuracy stability of product and reduce the cost of buying mould.
In order to solve the problem existing for background technology, the present invention is by the following technical solutions: it comprises interior membrane body, circulatory flow, aperture, oil-out; Interlock in interior membrane body and be provided with several circulatory flow, the afterbody of interior membrane body is provided with several aperture, and the middle part of interior membrane body is provided with several oil-out, and aperture and oil-out all communicate with circulatory flow.
Described aperture is fuel-displaced hole.
In cold drawing process of the present invention, in aluminum pipe lubricating oil by the aperture continuous lubrication of lubrication cold drawing internal mold afterbody capable of circulation to the work strip position of internal mold front portion and deformed area, reduce the heat of cold drawing internal mold work strip and deformed area, by lubricating oil circulate decrease core print glue aluminium phenomenon and add single wire drawing amount; Due to the minimizing of polishing number of times, consequently reduce the probability that the internal mold size that causes because of polishing reduces, thus improve the dimensional accuracy stability of product and reduce the cost of buying mould.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention;
Fig. 2 is the top view of Fig. 1.
Detailed description of the invention:
Referring to Fig. 1 and Fig. 2, this detailed description of the invention by the following technical solutions: it comprises interior membrane body 1, circulatory flow 2, aperture 3, oil-out 4; Interlock in interior membrane body 1 and be provided with several circulatory flow 2, the afterbody of interior membrane body 1 is provided with several aperture 3, and the middle part of interior membrane body 1 is provided with several oil-out 4, and aperture 3 and oil-out 4 all communicate with circulatory flow 2.
Described aperture 3 is fuel-displaced holes.
In this detailed description of the invention cold drawing process, in aluminum pipe lubricating oil by the aperture continuous lubrication of lubrication cold drawing internal mold afterbody capable of circulation to the work strip position of internal mold front portion and deformed area, reduce the heat of cold drawing internal mold work strip and deformed area, by lubricating oil circulate decrease core print glue aluminium phenomenon and add single wire drawing amount; Due to the minimizing of polishing number of times, consequently reduce the probability that the internal mold size that causes because of polishing reduces.
This detailed description of the invention reduces the heat of cold drawing internal mold work strip and deformed area, decreases the probability that the internal mold size that causes because of polishing reduces, thus improves the dimensional accuracy stability of product and reduce the cost of buying mould.
